Research on multi-channel wireless power distribution switch

This paper introduces the structure of the direct current power distribution system and the application of the wireless power distribution switch (WPDS), analyzes the operation mode of the WPDS, designs the wireless power transfer unit with high efficiency and the bi-directional communication unit in order to achieve wireless power switching and load current sensing in each channel at the same time. With the WPDS, bulky cables and switches can be saved and the problem of electric sparks is eliminated, reducing weight of the power distribution system and improving the lifetime of the power distribution switches.
